ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

How to Build an Entity Relationship Diagram (ERD)

Mathematics Symbols

ConceptDraw DIAGRAM extended with Mathematics solution from the Science and Education area is a powerful diagramming and vector drawing software that offers all needed tools for mathematical diagrams designing.
Mathematics solution provides 3 libraries with predesigned vector mathematics symbols and figures:
Solid Geometry Library, Plane Geometry Library and Trigonometric Functions Library.

Mathematics

Mathematics solution extends ConceptDraw DIAGRAM software with templates, samples and libraries of vector stencils for drawing the mathematical illustrations, diagrams and charts.

ER Diagram Styles

When creating ER diagrams, you can apply different color ER diagram styles and also notation styles. ConceptDraw DIAGRAM enhanced with Entity-Relationship Diagram (ERD) Solution gives the ability to draw visual and attractive ER Diagrams using the style icons from Crow’s Foot notation and Chen's notation professionally designed and offered by ERD Chen's Notation and ERD Crow’s Foot Notation libraries.

Optimize a Workflow

The first step to optimize a workflow is to get its visual depiction. Then you can analyse and optimize the workflow making changes to your workflow diagram. We recommend to use ConceptDraw DIAGRAM software extended with the Workflow Diagram solution to visualize and optimize your workflow. It allows you produce easy-to-change scalable vector graphic workflow and then present it to your team or partners.

E-R Diagrams

Complexity of databases increases day by day, due to this the Entity relationship models and E-R diagrams become more and more popular, and now are an important part of database design. E-R diagrams created at ConceptDraw DIAGRAM allow visually and graphically represent structure and design of databases.

IDEF4 Standard

Use Case Diagrams technology. IDEF4 standard implies not only graphical presentation but the additional information about diagrams of heredity, methods systematization and types which are contained in specifications.

Scientific Symbols Chart

ConceptDraw DIAGRAM is the beautiful design software that provides many vector stencils, examples and templates for drawing different types of illustrations and diagrams.

Mathematics Solution from the Science and Education area of ConceptDraw Solution Park includes a few shape libraries of plane, solid geometric figures, trigonometrical functions and greek letters to help you create different professional looking mathematic illustrations for science and education.

ERD Symbols and Meanings

The vector stencils library "Professions" contains 58 people clipart images of different professions you can use in your presentations, illustrations and infographics.
"Electronic clip art is available in several different file formats. It is important for clip art users to understand the differences between file formats so that they can use an appropriate image file and get the resolution and detail results they need.
Clip art file formats are divided into 2 different types: bitmap or vector graphics. ...
In contrast to the grid format of bitmap images, Vector graphics file formats use geometric modeling to describe an image as a series of points, lines, curves, and polygons. Because the image is described using geometric data instead of fixed pixels, the image can be scaled to any size while retaining "resolution independence", meaning that the image can be printed at the highest resolution a printer supports, resulting in a clear, crisp image. Vector file formats are usually superior in resolution and ease of editing as compared to bitmap file formats, but are not as widely supported by software and are not well-suited for storing pixel-specific data such as scanned photographs. In the early years of electronic clip art, vector illustrations were limited to simple line art representations." [Clip art. Wikipedia]
The clip art example "Professions - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the People solution from the Illustration area of ConceptDraw Solution Park.
